Abstract
A camshaft adjuster () for an internal combustion engine is provided, wherein the relative angle between a drive wheel () and an inner rotor associated with a camshaft can be adjusted via hydraulic loading of pressure spaces () between an outer rotor () and the inner rotor (), wherein the drive wheel () is made of plastic and the outer rotor () associated with the drive wheel () is made of metal. Particularly good linkage can be obtained and mounting complexity can be reduced by having at least one bearing surface between the outer rotor () and the inner rotor () that is connected with a firmly bonded material or positive fit in the drive wheel that is made from plastic.
